The http://www.taitale.com/?page=product_redeem page is there to list the items you own. You can add more items if you wish you do not need to; the Steam Key will be redeemable soon when we launch the live server as the steam key will bind access to your account.

The other items will also be available to redeem when they are ready. When items are redeemable a button will appear next to them similar to the GIFT button.
